The Government of Canada's Fuel Life Cycle Assessment Model (the Model) is a tool to calculate the life cycle carbon intensity (CI) of fuels and energy sources used and produced in Canada. The Model is used to determine the CI of hydrogen for the purpose of creating tax credits under the Clean...

Lake Winnipeg usually experiences ice cover during December to May (South Basin)/ June (North Basin). This dataset are water quality data collected in the South Basin of Lake Winnipeg during the winter of 2024, for the Freshwater Lake Winnipeg project. The bottom part (10cm) of ice-core samples...

This data set contains concentrations of polychlorinated dibenzodioxins and dibenzofurans in wastewater Influent (INF), Effluent (EFF), Landfill Leachate (LCH), Biosolids (BIOS) and/or Sludge (SLG) sampled from various Wastewater Treatment Plants (WWTPs) and Landfills across Canada.

This data set contains concentrations of chlorinated paraffins in wastewater Influent (INF), Effluent (EFF), Landfill Leachate (LCH), Biosolids (BIOS) and/or Sludge (SLG) sampled from various Wastewater Treatment Plants (WWTPs) and Landfills across Canada.

This study aimed to determine whether the pharmaceutical metformin had toxicological effects on the fathead minnow (Pimphales promelas) in their various life stages—from eggs to adulthood. Endpoints included survival, growth, and reproductive development. Fathead minnows were exposed to metformin...

This study aimed to provide insights into how climate-driven diet shifts may impact contaminant exposures of Arctic species. We compared feeding ecology and contaminant concentrations in ringed seals (Pusa hispida) from two Canadian sub-Arctic (Nain and Arviat) and two Arctic sites (Sachs Harbour...

The Multi-Sector Air Pollutants Regulations set air pollution emission standards across Canada for several industrial sectors. They limit the amount of nitrogen oxides (NOx) emitted from gaseous fuel-fired non-utility boilers, heaters and stationary spark-ignition gaseous fuel-fired engines. They...

This data set contains concentrations of perfluoroalkyl and polyfluoroalkyl substances (PFAS) in wastewater Influent (INF), Effluent (EFF), Landfill Leachate (LCH), Biosolids (BIOS) and Sludge (SLG) sampled from various Wastewater Treatment Plants (WWTPs) and Landfills across Canada. Scientific...

We publish Canada’s greenhouse gas (GHG) and air pollutant emissions projections each year. The GHG emissions projections help us measure progress in reducing greenhouse gas emissions and combating climate change. GHG emissions projections are presented for a few scenarios. The air pollutant...

As part of a scientific assessment of critical habitat for boreal woodland caribou (Environment Canada 2011, see full reference in accompanying documentation), Environment Canada's Landscape Science and Technology Division was tasked with providing detailed anthropogenic disturbance mapping,...

With the changing climate conditions, marine traffic along Canada’s coastal regions has increased over the past couple of decades and the need to improve our state of preparedness for oil-spill-related emergencies is critical. Baseline coastal information, such as shoreline form, substrate, and...

Tire wear particles end up on roads where they may run off into nearby rivers and lakes by rain and snowmelt. This study examined how toxic these tire particles are to eggs and the newly hatched larvae of the fathead minnow (Pimephales promelas). Tire particles were finely ground up and were...

This study aimed to identify chemical components that could distinguish chemical mixtures in oil sands process-affected water (OSPW) from natural groundwater sources. Oil sands process-affected samples were collected from two different oil sands development tailing ponds, and natural groundwater...

The Water Survey of Canada provided a digital archive of river ice thickness measurements at four hydrometric monitoring stations along the Liard River. The average ice thickness measurements were extracted and compiled to the attached .csv file. The stations include: Liard River at Upper...

This dataset displays the geographic areas within which critical habitat (CH) for terrestrial species at risk, listed on Schedule 1 of the federal Species at Risk Act (SARA), occurs in Canada. Note that this includes only terrestrial species and species for which Environment and Climate Change...

Under the Clean Fuel Regulations (CFR), registered creators, foreign suppliers and carbon-intensity contributors can use the Fuel Life Cycle Assessment (LCA) Model to calculate a carbon intensity (CI) for the purposes of creating credits. In order to calculate those CIs, the following documents...

The Canadian Aquatic Biomonitoring Network (CABIN) is an aquatic biomonitoring program for assessing the health of fresh water ecosystems in Canada. Benthic macroinvertebrates are collected at a site location and their counts are used as an indicator of the health of that water body....

The Atlantic dataset is part of Environment and Climate Change Canada’s Shoreline Classification and Pre-Spill database. Shoreline classification data has been developed for use by the Environmental Emergencies Program of Environment and Climate Change Canada for environmental protection...

The Metal Mining Effluent Regulations came into force in 2002 pursuant to the Fisheries Act to regulate the deposit of mine effluent and mine waste into waters frequented by fish. The Metal Mining Effluent Regulations were amended in 2018, and are now known as the Metal and Diamond Mining...

In 2006, the Government of Canada initiated the Chemicals Management Plan (CMP), which takes action regarding chemicals that are harmful to human health or the environment. One element of the CMP is Monitoring and Surveillance, which generates data on the presence and levels of chemical...
